Can June use an antivirus program in this case and would it be effective against a polymorphic virus?

June, a security analyst, understands that a polymorphic virus has the ability to mutate and can
change its known viral signature and hide from signature-based antivirus programs. Can June use
an antivirus program in this case and would it be effective against a polymorphic virus?

A.
Yes. June can use an antivirus program since it compares the parity bit of executable files to
the database of known check sum counts and it is effective on a polymorphic virus

B.
Yes. June can use an antivirus program since it compares the signatures of executable files to
the database of known viral signatures and it is very effective against a polymorphic virus

C.
No. June can’t use an antivirus program since it compares the signatures of executable files to
the database of known viral signatures and in the case the polymorphic viruses cannot be
detected by a signature-based anti-virus program

D.
No. June can’t use an antivirus program since it compares the size of executable files to the
database of known viral signatures and it is effective on a polymorphic virus
